Yet, most people agree with you, that a player is more likely to be banned/punished for chat offenses than AFK/INT. The how and why of it all, is the actual discussion. When these forums had CS reps, they said players overreported for Chat Abuse and underreported for everything else. As I’ve said to you, I agree that Blizz should play a more active role in detecting the most egregious forms of game griefing, but we are where we are with Hots.
Some good news for you, just as when someone is punished for AFK, you won’t receive an email, or any official word from Blizzard, it would seem Blizz is cleaning house nonetheless.
